JAR SEALER Filed May 22, 1955 Jm e5 F0 2 2630 INVENTOR ATTORNEY Patented Apr. 13, 1937 UNETED STATES PATENT OFFICE JAR SEALER Application May 22,

1 Claim.

This invention relates to jar sealers, and its general object is to provide a. sealing device that is primarily designed for use on caps of Mason jars and the like for removing kinks, raised places and the like from the flanged lower edge of the skirt thereof, with the result the edge will be straightened made uniform throughout its circumference so as to cooperate with the rubber sealing element or gasket to provide a perfect and air-tight joint between the jar and its cap.

Another object of the invention is to provide a jar sealing device for the purpose of reshaping jar caps so that they can be used from time to time, and the device accomplishes its function in an easy and expeditious manner, with very little effort on the part of the operator.

A further object of the invention is to provide a jar sealing device that includes a body formed from a single piece of sheet metal, in a manner to provide opposite walls that have journaled thereto, cap flange engaging rollers to straighten the flange for the purpose previously set forth.

A still further object of the invention is to provide a jar sealing device, that is simple in construction, inexpensive to manufacture and extremely efficient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a top plan view of the sealing device which forms the subject matter of the present invention.

Figure 2 is a side View thereof.

Figure 3 is a vertical sectional view taken through the device and illustrates the same in applied position.

Referring to the drawing in detail, it will be noted from Figure 3 that I have illustrated my device as being applied to the cap of the usual Mason jar, and for distinction, the cap is indicated by the letter A and the jar by the letter B.

The body of my device is hollow and preferably formed from a single piece of sheet metal into octagon shape, and includes a top I having depending from each of the straight edges thereof a wall 2. The walls of course have their side edges integral. Due to the octagon shape of the body, it will be obvious that eight depending walls 1935, Serial No. 22,848

or portions are provided that are disposed at an angle with respect to each other, consequently the body can be gripped at any place desired, as the walls provide a convenient gripping surface, during the use of the device, as will be apparent. The 5 top I may be flat but I have shown a plurality of concentrically arranged annular ribs 3 formed therein andrising therefrom, as best shown in Figure 3.

While I preferably provide four cap flange en- 10 gaging rollers, any number may be employed, providing they are arranged to balance each other. These rollers are indicated by the reference numeral 4 and are in the form of disks shaped to provide annular heads 5, the outer walls of which 15 are inclined outwardly to form flange engaging faces 6.

In the form as shown, the rollers 4 are journaled to certain of the walls 2 which are disposed opposite each other as best shown in Figure 1, and the journals are in the form of headed pins 1 having bearings 8 to receive the rollers and for disposing them inwardly of the walls, as best shown in Figure 3. The pins may be riveted or otherwise secured to the walls, as will be apparent, but in any event, the flange engaging faces extend below the lower edge of the walls, to allow ample space between the lower edge and the top of the body of the jar B.

From the above description and disclosure of 30 the drawing, it will be obvious that I have provided a jar sealing device that is primarily designed for reshaping the flanged lower edges of jar caps, and in the use of my device, the cap A is applied to the jar B in the usual manner, and of course with the gasket between the flange of the cap and the gasket receiving seat. The device is then arranged, with the body enclosing the cap so that the rollers engage the lower edge thereof, as shown in Figure 3. The device is rotated while applying slight pressure thereto, with the result raised places and the like are removed from the lower edge, therefore the latter will cooperate with the sealing element or gasket to provide a leak proof and air-tight connection between the cap and jar.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is:

disk rollers journaled to certain opposed walls and arranged within the chamber, and said rollers shaped to provide hollow annular heads at the peripheries thereof, with the outer walls of the beads outwardly flared in rounded formation to 5 provide cap flange engaging surfaces.
